Question
The exchange of genetic material between chromatids of paired homologous chromosomes during first meiotic division is called
Options
A.transformation
B.chiasmata
C.crossing over
D.synapsis
Solution
In pachytene stage of prophase -I of meiosis, there is breakage and reunion of chromatids, it results in exchange of segments between non-sister chromatids of a bivalent, known as crossing over. It leads to recombination of linked genes / alleles and is a major source of continuous type of genetic variations in sexually reproducing organisms.
